Objective To compare the clinical efficacy of intravenous polymyxin B alone and intravenous drip combined with nebulized inhaled polymyxin B in treatment of patients with carbapenem-resistant organism (CRO) pneumonia. Methods The clinical data of 85 patients with CRO pneumonia admitted to the Intensive Care Unit of Nanjing Drum Tower Hospital from September 2020 to June 2023 were collected using a retrospective study. According to the different ways of administration of polymyxin B, the patients receiving polymyxin B intravenous drip therapy alone were included in group A, and the patients receiving polymyxin B intravenous drip therapy combined with nebulized inhalation therapy were included in group B. The therapeutic effective rate, bacterial clearance rate, 30-day all-cause mortality and the level of infection indexes before and after the use of medication were compared between the two groups. The occurrence of acute kidney injury during the use of drugs in the two groups was observed and recorded. Results The pathogenicity culture results showed that there was no statistically significant difference between the two groups (P=0.144). Serum procalcitonin and C-reactive protein were significantly lower in the two groups after drug administration compared with those before drug administration (both P<0.05). The therapeutic efficiency and bacterial clearance rate in group B were higher than those in group A (both P<0.05). There was no statistically significant difference in 30-day all-cause mortality between the two groups (P=0.664). And there was no statistically significant difference in the incidence of adverse reactions between the two groups (P=0.650). Conclusion When polymyxin B is used to treat patients with CRO pneumonia, the intravenous drip combined with nebulized inhalation regimen is superior to intravenous drip therapy alone and does not increase the risk of developing nephrotoxicity.
Objective To investigate the cl inical directive significance of three-dimensional reconstruction of CT in treating mandibular angle hypertrophy. Methods Between March 2009 and January 2011, 18 patients with mandibular angle hypertrophy were treated using the three-dimensional reconstruction technology of CT. All patients were female, aged20-36 years with an average of 25 years. Eighteen patients included: 14 single mandibular angle hypertrophy, 3 mandibular angle hypertrophy with masseter hypertrophy, and 1 mandibular angle hypertrophy with bilateral asymmetry; 6 cases of ptosis of mandibular angle, 9 cases of prominent mandibular angle, and 3 cases of introversive mandibular angle. According to the types of mandibular angle hypertrophy, the surgical methods could be correctly chosen. The procedure was planned and simulated; the osteotomy l ine was marked and the osteotomy was measured on the workstations of three-dimensional reconstruction. Results No fracture of mandible occurred in the operation. Facial nerve temporary attack occurred in 1 case and recovered at 3 months after operation. All patients were followed up 6-12 months (mean, 7.6 months). After 6 months of operation, the effectiveness was satisfactory in 15 cases, basically satisfactory in 2 cases, and unsatisfactory in 1 case (bilateral asymmetry). Conclusion Based on three-dimensional reconstruction technology of CT, surgical design performed on the model will promote the accuracy of operation. Basically symmetrical appearances can be achieved with satisfactory results.
ObjectiveTo analyze the biomechanical properties of the rod-screw prosthesis based on a pelvic three-dimensional finite element model including muscle and ligament, and evaluate the effectiveness of zoneⅠ+Ⅱ+Ⅲ reconstruction of hemipelvis with rod-screw prosthesis in combination with clinical applications. Methods A total of 21 patients who underwent hemipelvic tumor resection (zoneⅠ+Ⅱ+Ⅲ) and rod-screw prosthesis reconstruction between January 2015 and December 2020 were selected as the research subjects. Among them, there were 11 males and 10 females; the age ranged from 16 to 64 years, with an average age of 39.2 years. There were 9 cases of chondrosarcoma, 7 cases of osteosarcoma, 3 cases of Ewing sarcoma, and 2 cases of undifferentiated pleomorphic sarcoma. According to the Musculoskeletal Tumor Society Score (MSTS) staging, there were 19 cases of stage ⅡB and 2 cases of stage Ⅲ. Preoperative Harris Hip Score (HHS) and MSTS score were 54.4±3.1 and 14.1±2.0, respectively. Intraoperative 15 cases underwent extensive resection, 5 cases underwent marginal resection, and 1 case underwent intralesional resection. The CT image of 1 patient after reconstruction was used to establish a three-dimensional solid model of the pelvis via Mimics23Suite and 3-matic softwares. At the same time, a mirror operation was used to obtain a normal pelvis model, then the two solid models were imported into the finite element analysis software Workbench 2020R1 to establish three-dimensional finite element models, and the biomechanical properties of the standing position were analyzed. The operation time, intraoperative blood loss, and operation-related complications were recorded, and the postoperative evaluation was carried out with HHS and MSTS scores. Finally, the local recurrence and metastasis were reviewed. ResultsFinite element analysis showed that the peak stress of the reconstructed pelvis appeared at the fixed S1, 2 rod-screw connections; the peak stress without muscles was higher than that after muscle construction, but much smaller than the yield strength of titanium alloy. The operation time was 250-370 minutes, with an average of 297 minutes; the amount of intraoperative blood loss was 3 200-5 500 mL, with an average of 4 009 mL. All patients were followed up 8-72 months, with an average of 42 months. There were 7 cases of pulmonary metastasis, of which 2 cases were preoperative metastasis; 5 cases died, 16 cases survived, and the 5-year survival rate was 72.1%. There were 3 cases of local recurrence, all of whom did not achieve extensive resection during operation. The function of the affected limbs significantly improved, and the walking function was restored. The HHS and MSTS scores were 75.2±3.0 and 20.4±2.0 at last follow-up, respectively, and the differences were significant when compared with those before operation (t=22.205, P<0.001; t=11.915, P<0.001). During follow-up, 2 cases of delayed incision healing, 2 cases of deep infection, 1 case of screw loosening, and 1 case of prosthesis dislocation occurred, and no other complication such as prosthesis or screw fracture occurred. Conclusion The stress and deformation distribution of the reconstructed pelvis are basically the same as normal pelvis. The rod-screw prosthesis is an effective reconstruction method for pelvic malignant tumors.
ObjectiveTo investigate the effectiveness of interrupted suture under exercise position in total knee arthroplasty (TKA).MethodsEighty-four patients with osteoarthritis who were treated with TKA between July 2015 and July 2016 were enrolled in the study. All patients were randomly divided into control group and observation group with 42 cases in each group. There was no significant difference in gender, age, side, body mass index, and osteoarthritis grading between 2 groups (P>0.05). The incisions were interrupted sutured at the knee flexion position in control group and at the exercise position in observation group. Preoperative and postoperative treatments of 2 groups were same. The incision length, suture time, total tramadol usage, intraoperative blood loss, stitches removal time, hospitalization time, incidence of postoperative complication, the incision healing score (HWES), and satisfaction score of incisional self evaluation (Liktert score) were recorded and compared between 2 groups. The visual analogue scale (VAS) score was used to evaluate the incision pain at pre- and post-operation. The hospital for special surgery (HSS) score and range of motion (ROM) were also used to assess the knee function.ResultsThere was no significant difference in incision length, incidence of postoperative complication, HWES score, stitching time, and hospitalization time between 2 groups (P>0.05). The suture time, intraoperative blood loss, and Likter score were significantly lower in control group than those in observation group (P<0.05), but the total tramadol usage was significantly higher in control group than that in observation group (P<0.05). All patients were followed up. The follow-up time ranged from 12 to 24 months (mean, 14.7 months) in control group and from 12 to 23 months (mean, 15.3 months) in observation group. There was no significant difference in VAS scores between 2 groups before operation, before going to bed at the 1st day, and after suture removal (P>0.05). The VAS score of observation group after flexion and extension exercises at the 1st day was significantly lower than that of control group (P<0.05). There was no significant difference in HSS score and ROM between 2 groups before operation and at 12 months after operation (P>0.05). The HSS score and ROM in observation group at discharge and at 1, 3, and 6 months after operation were superior to those in control group (P<0.05).ConclusionCompared with interrupted suture at flexion knee position, the application of interrupted suture at exercise positon in TKA had the advantages of less postoperative pain and good incision healing, and can get satisfactory early joint function recovery. But significant difference in the long-term effectiveness of the two methods was not found.

ObjectiveTo investigate the effect of fasttrack (FT) and traditional care (TC) on patients with rectal cancer underwent different surgical strategies in perioperative period. MethodsThe clinical data of 285 patients with rectal cancer from January 2009 to January 2010 in this hospital were retrospectively analyzed. These patients underwent high anterior resection (HAR) or lower/super lower anterior resection (LAR) under FT and TC were divided into four groups: FT+HAR (n=39), FT+LAR (n=17), TC+HAR (n=151), and TC+LAR (n=78), and intraoperative conditions and postoperative rehabilitation were analyzed. ResultsThe baselines characteristics of four groups were basically identical (Pgt;0.05). ①The operative time and blood loss of patients in four groups were not statistically significant (Pgt;0.05). ②Anastomotic leakage occurred in three cases, wound infection in 13 cases, and intestinal obstruction in four cases after operation, and the difference was not significant in four groups (Pgt;0.05). ③The time of first defecation and first flatus of four groups were not statistically significant (Pgt;0.05), but there were significant differences in the time with drainage tube, nasogastric tube, and catheter tube, the time of first intake and first ambulation, and length of stay among four groups (Plt;0.05). Compared with TC+HAR and TC+LAR group, the time with drainage tube, nasogastric tube, and catheter tube, and the time of first intake and first ambulation of patients were shorter in FT+HAR and FT+LAR group, and the length of stay of patients in FT+LAR group was shorter than that in TC+HAR group and TC+LAR group (Plt;0.05). ConclusionsFT can promote postoperative rehabilitation of rectal cancer patients underwent different surgical strategies, but which does not demonstrate the superiority of reducing postoperative complications.
